vented new and useful Improvements in- Appliances for Fireplaces, ofwhich the. following is a specification.

The purpose of the invention is to provide an air heatin device for usein conjunction with open ire places whereby a column of air ismaintained interposed between the fire and the walls of the fire place,cold air being taken in at approximately the floor level and beingreturned in a heated cond tion to the roof in which the fire place 15used. To this end, the invention comprlses preferably a pair of hollowelements or members adapted fordisposition in the fire place andprovided with means for supporting a coal grate, if coal is used,themembers having floor level intake openings and discharge openingspositioned at the top of the fire place and adapted to discharge heatedair into the room at this level.

While illustrated and described in a specific embodiment the inventionis not to be restricted to such embodiment. The right is reserved tomake such changes or alterations as the actual reduction to practice maysuggest, in so far as such changes or alterations are compatible inspirit with -'the annexed claims.

In the accompanying drawmgs:-

Figure '1, is a front elevational view of anopen fire place equippedwith the appliance.

- constituting the invention.

- Fig. 2, is a perspective'view of one of the elements comprised in theinvention.

Adapted for use with any open fire place, but designed particularly foruse with those having a coal grate, the invention comprisescomplementary hollow elements each having a substantially rectangularshaped body 1 and in front wall of which there is provided an airentrance opening 2. The upper end a of the body element is contractedinto a neck 3 terminating in an upwardly disposed discharge opening 4:.On one side the body element is equipped with the lugs 6 by means ofwhich it is secured in the fire place 7 by engagement with the lugs 8carried on the. side walls thereof. The body element is alsoequippedwith the In 9 to be engaged by the lugs 10 carrie by the grate11. The two members comprising the invention are disposed-respectivelyon opposite sides of the fire place and through the mstrumentality ofthe lugs 9 support the grate 11.

Each member at the rear is provided with a lateral hollow element 12,these two elements of the two members serving as a back wall for thefire place and against which the heat from the ate ma be directed aswell as against the lnner si e walls of the body members.

A great deal of heat is lost in open fire places, as a'result ofdissipation into the walls of the fire place and as a result of pas sageup the chimney. The appliance herein described aims to conserve a largequantity of this lost heat. All cool air being near the level of thefloor will pass through the intake openings 2 and into the body elements1 to the lateral extensions 12 of the two members and therein will beheated, rising to pass out of the discharge openings 4 4 and in this waythe quantity of air drawn into the appliance from the room and returnedin a heated condition, may be determlned to suit the conditions ortemperature of the room.

The elements comprising the appliance may be made of cast iron or sheetsteel or any acceptable material and conditions of manufacture willobviously determine this. The invention having been described, what isclaimed as new and useful is 1. The combination with an open fire place,of a removable heating appliance consisting of complemental hollowmembers each of which is formed with a hollow body portion disposedagainst the side wall of the 'fire place, the said body portions beingformedwith laterallyprojecting hollow elements disposed against the backwall of the fire place and having contracted discharge mouths projectingforwardly from the fire place and terminating above the top thereof,

the said body elements having substantially floor level intake openingsfor the purpose specified.

2. The combination with an open fire place, of complemental hollowelements each of which consists of a body element having means forattachment to one side wall of the fire place, the said body elementbeing formed With a. hollow laterally projecting element disposedagainst the back wall of the fire place and abutting end-on thecorresponding element of the complcmental member, both members havingtheir body elements contracted at their upper ends to provide dischargeopenings above the plane of the top of the fire place and havingsubstantia-lly floor level intake openings, a rate suspended from thebody elements 0 the two'members, and dampers carried in said bodyelements above the plane of thetop of the laterally projecting elementsin the manner and for the purpose specified.

In testimony whereof I aflix my signature. PEYTON W. WILLIAMS.
